I connect monitor to lenovo laptop and both screens go black.
Posted on 2014-02-02
Windows 7 pro lenovo t500 with HW194D monitor.
Quick explanation -- I can't get my external monitor to work.
much longer explanation:
After a year with no external monitor problems, today things got bad, then got worse.
My laptop usually is off when I get to the office, but today it was on when I left home.
I came into the office and plugged in my mouse, keyboard, cat5, vga monitor and power.
Both the LCD and the monitor worked, and showed the same cloned screen which is normal. At this point I would normally shut the lid and push the lenovo out of the way. but right away things looked weird, the resolution on the monitor was wrong and the Icons looked bigger than normal.
Anyway, I didn't worry much about that odd resolution, so I shut the lid and THE MONITOR WENT BLACK !!!!. I opened the laptop and both screens came on.
In my many attempts to fix it I tried a half dozen things and made it worse.
For a half hour, I could not even plug the monitor in because BOTH screens would be black! Luckily, disconnecting the monitor would cause the LCD to come back on, but it was scary.
Eventually, I figured a way to fix the "both are black" problem. I used windows key P which normally brings up a display switcher dialog showing (lcd only, clone, extended, projector only.) normally, I can see those choices, but since both displays were black I was flying blind. I used the tab twice and hit enter, which seems to have been the right combination because both black screens became visibile as screen 1 and 2 in extended mode.
But, I don't like extended mode, so I then tried Projector only, and everything went to h**l again.
Now the only mode I can get to work is LCD only and I am thinking about throwing everything out the window and becoming a beach bum.
